Beds

Pull out any large weeks and lay cardboard, Permatex, black plastic (ie compost bags opened up), or mulch to suppress weeds.  This has the added advantage of warming the soil.

Avoid digging the soil or treading on soil when it’s waterlogged to prevent compaction.

Crops

Pull up any remaining winter crops or rotting vegetation.

Add Organic Matter

Add any organic matter (well-rotted manure or compost) to improve the soil.

Pruning Fruit Trees & Bushes

As the plants are dormant now is a good time to prune back fruit trees and bushes.  This will encourage new growth in the spring and help to reduce disease.

Sow seeds 

Start seeds indoors: Peas (including sweet peas) kale, leeks, tomatoes, chillies peppers, can be sown in the greenhouse or under cover

Plant bare-root fruit bushes and trees

If ground is not frozen or waterlogged and workable, you can plant bare-rooted plants (such as raspberries and strawberries) and trees.  If you want a splash of colour lots of supermarkets stock bare-root shrubs.

Remember to check the weather

It can still be bitterly cold in February so makes sure you keep plant protection in place and shield vulnerable plats with fleece from any late frosts

Clean tools and sheds

Even if you can’t actually do anything on the allotment, you can still clean and oil garden tools and pots/containers of seed sowing.  It is also a good time to get any large equipment serviced
